OpenLIT

Trace, evaluate, and monitor AI applications with OpenTelemetry.

Meet OpenLIT

OpenLIT is an open-source platform for understanding and improving AI applications and agents. It collects traces for model calls, tools, and retrieval steps, then connects them with latency, cost, and evaluation results. Developers can inspect individual sessions, compare models, and use evidence from production traffic or experiments to investigate quality problems.

The platform also includes prompt versioning, API key management, and GPU monitoring. Teams can instrument applications with supported SDKs or send existing OpenTelemetry data to their own installation. Its self-hosted edition provides a shared place to follow an AI workflow from development through deployment and ongoing operation.
